Least Common Multiple of 813, 1809

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

• Least Common Multiple of 813, 1809 by common division method
• Least Common Multiple of 813, 1809 with GCF Formula

∴ So the LCM of the given numbers is 3 x 271 x 603 = 490239

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 813,1809 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(813,1809) = 3

common factors(in case of two or more numbers have common factors) = 1

GCF(813,1809) x common factors =3 x 1 = 3

LCM(813,1809) = ( 813 × 1809 ) / 3

LCM(813,1809) = 1470717 / 3

LCM(813,1809) = 490239

∴ Least Common Multiple of 813,1809 is 490239

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 424, 8265
• LCM of 315, 8968
• LCM of 820, 7270
• LCM of 228, 3555
• LCM of 118, 5862
